Function combatant_character_state

pub fn combatant_character_state<'a>(
    character_state: &'a CharacterState,
    party: &'a Party,
    pvp_state: &'a Option<PVPState>,
    fight: &ActiveFight,
    entity_id: EntityId,
) -> Option<&'a CharacterState>

The durable CharacterState behind combatant entity_id in this session’s fight — the local hero’s, the party ally’s, or a human PvP opponent’s. None for mobs and for arena filler bots, which have no CharacterState.

Takes the sibling OverlordState fields separately so a caller can keep borrowing active_fight mutably while the returned build is alive.
